Abstract

The invention relates to a plant remediation technology of lead-polluted soil, and in particular relates to an application of melastoma dodecandrum in remediation of lead-polluted soil. The melastoma dodecandrum is planted on the soil containing lead pollutants; lead in the polluted soil is massively absorbed by the root of the melastoma dodecandrum and is transferred to an overground part organ; when the plant grows to the overground part and the biomass is maximum, the overground part organ of the plant is taken away from the polluted soil, so that the aim of removing the lead pollutants from the soil is fulfilled. Because the lead-polluted soil is treated by utilizing the enrichment plant melastoma dodecandrum, the application of the ornamental sunflower has the advantages of low cost and high operability, and has a good effect in prevention of wind erosion and water erosion of the polluted soil; and moreover, the physical and chemical properties of soil cannot be destroyed and secondary pollution is avoided.

Description

technical field

[0001] The invention relates to a phytoremediation technology for lead-contaminated soil, strictly speaking, it is a method for repairing lead-contaminated soil by using Verbenaceae plant brocade, that is, the application of the brocade in repairing lead-contaminated soil. Background technique

[0002] Lead is one of the main heavy metal pollutants in the environment. Soil lead pollution is widespread in my country and around the world, especially around mines, smelters and roads, where lead pollution is more serious. Once lead enters the human body, it will interfere with the normal work of nerve cells through the blood, destroy the survival of hemoglobin in the blood and the permeability of brain microvessels, which can lead to retarded and unsound brain development, and ultimately affect people's intelligence. Therefore, lead pollution Soil management and restoration is a very urgent task. Contaminated soil phytoremediation technology is cheap, does not d...
